Implemented notification hub with networking on branch andrew/notifications

[AndrewG828]

Overview

Implemented notification hub with swipe to mark read, filtering by notification hub, filtering by createdAt date, networking to pull recent notifications, and error screen for empty notifications and api errors.

Changes Made

• Refactored Notification struct to reflect backend data from api.
• Refactored NotificationView to actually display notification data from the filtered notifications array.
• Implemented new NotificationSection enum to filter notifications by when they were created at to display different headers for notifications created at different times (New, Last 7 Days, etc.).
• Implemented new LoadState enum method to display different screens on notification hub if the notifications are empty, successful, idle, or if there is an error in the api call.
• Implemented preliminary networking (need to test still)
• Refactored dummy data for testing purposes to align with new struct.

Test Coverage

• Used dummy data and changed LoadState enum to test on iOS emulator.

Next Steps

• Need to set up local backend to test networking.
